TORSION-SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 417,041, dated December 10, 1889.

Application filed October 4, 1889. $erial No. 325,985. (No model.)

To all whom it may concern screws, or other means 6, while their outer Be it known that I, EDWIN JARRELL, a ends pass loosely through journal-boxes 7 7, resident of Harper, in the county of Harper formed for them in the end cross-bars 1 1. and State of Kansas, have invented certain To admit of the free torsional action of these 55 new and useful Improvements in Torsional bars, and also give increased strength at a Springs for Vehicles; and I do hereby declare point where it is essential, a round sleeve 8 the following to be a full, clear, and exact deis formed at the points where the bars extend scription of the invention, such as will enable through the journals. Just beyond these others skilled in the art to which it apperpoints the bars are bent outward to form the 60 IO tains to make and use the same. arms 9 9, upon which thebody is supported.

My invention relates to an improvement in These arms may be variously bent, but preftorsional springs for vehicles, the primary oberably extend out at right angles to the box. ject being to provide a durable and yielding The journals in the cross-bars, through spring which shall be productive of ease and which the spring-bars pass, may be variously 5 I5 comfort to the occupant of the vehicle. formed.

The self-oiling journal is made by passing In the accompanying drawings, Figure 1 is the spring through the plug, as shown in Fig. a bottom plan View of the vehicle-body with 8, through its edge, as shown in Fig. 9, or one form of spring attached.

Figs. 6 and 7 are washers, as in Fig. 12, and these washers may modifications, and Figs. 8, 9, 10, 11, 12, and be bent around the spring, as shown in Fig. 13 show different forms of oiling-plugs. 13. "When in this form, they may be held in 9 4 A represents the wagon-box, and 1 1 are a place by means of a pin driven back of them, pair of end cross-bars bolted or otherwise seand the pin, the same as the plugs, is held in cured on the lower side of the bottom of the place by a thin angle-plate 13, which laps over box, and 2 is a center cross-bar located beand is secured to two edges of the cross-bars. tween the end crossbars. In using wood plugs all the friction is on 95 A pair of spring-bars, preferably square or the end of the grain, both in the end of the angular in section, are bent substantially into plug and cross-bar. V shape and so placed that the bends 4: 4 The outwardly-projecting arms of the formed in them come together, or nearly so, springs, as above described, are supported on where they are clamped s ecurelyby means of the side bars 14 14 by the shackles 15 15: I 0 plates 5 5, which are held on each side of the These are made in different forms, as shown bars and to the center cross-bar 2 by bolts, in Figs. 5, 6, and 7, and consist of the plate 16, having dianietrically-located slots 17 17, by means of which the plates are adj ustably secured to the side bars at different angles to suit the position of the arms 9 9. A swinging knuckle is loosely supported on the plate and a bolt 18, passing through the knuckle, connects the ends of the arms. By means of these forms of shackles the arms are easily fastened to the side bars of the vehicle whatever position they may assume.

In Fig. 2 the bars 1 1, constituting the springs, are separated at the center into four parts or sections, which admit of their being adjusted laterally in the clamps, the object being to equalize strain. It is with this particular construction of spring that the adjustable shackles are rendered of importance, as the adjustment of the springs laterally makes the ends of the arms 9 9 take different posi tions relative to the side bars. The adj ustability of shackles admits of this, and also by the use of them the angle formed in the bars composing the springs may be an acute,

right, or obtuse angle. Another difference consists in the spirals 19-19 in the rear sections of the springs, which add to the clasticity of the springs and allow me to employ longer spring-bars in front for the purpose of making a slow-motion spring.

In Fig. 4 the spring-bars extend straight out of the end bars and the arms 9 9 extend forward and backward at right angles and are adapted for support on the front'barand axle of the vehicle.

These springs may be applied to other than four-wheeled vehicles, and it is evident that slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the particular construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is j 1. In a Vehicle, the combination, with a body having bearings on the under side thereof and supports for the body, of torsional springs each rigidly secured to the body and passing through its respective bearing and secured at its outer end to the supports for the body, and plugs saturated with a lubricant for lubricating the springs at the bearings, substantially as set forth.

2. The combination, with a vehicle box or body, of torsion-springs secured to the box or body and shackles for attaching the springs to the side or end bars of the running-gear, the said shackles having curved slots, substantially as set forth.

3. The combination, with a box and frame, of torsion-springs secured to the box at one end and extending loosely through bearings at the opposite end and shackles for connectin g the springs to the frame, the said shackles having curved slots to enable them to be turned or adjusted to receive the ends of the torsion-springs, substantially as set forth.

4. The combination, with a box and frame, of torsion spring-bars clamped at one end to the box and extending through self-oiling journals at the opposite ends, and adjustable shackles consisting of slotted plates, swinging knuckles, and bolts, substantially as set forth.

5. The combination, with a box, end and center cross-bars secured thereto, and vehicleframe, of a pair of substantially-V-shaped torsion spring-bars, clamps for holding these bars to the center cross-bar of the box, selfoiling journals carried by the box, through which the springs pass, and adjustable shackles for connecting the springs to the frame, substantially as set forth.

6. The combination, with a box, end and center cross-bars secured thereto, and'vehicle frame, of adjustable sectional torsionsprings, clamps for adjustably securing them at one end to the center cross-bar, journals in the end cross-bars, through which the springs pass, and shackles connected to the extreme outer ends of the springs for securing them to the side or end bars of the running-gear, substantially as set forth.

Intestimony whereof I have signed this specification in the presence of two subscribing witnesses.

EDWIN J ARRELL.
